To 'all wkomzt may concern:

Be it known that I, STEVE TAKcs, a subject of theEmperor of Austria-Hungary, residing at Newark,.in the county of Licking and State ofOhio, have invented certain new and useful Improvements in Wagons', of which the following is a specification.

iMy invention relates to wagons of the type designed for' use in conveying heavy 'and massive articles from place to place.

,The main vobject 0f-my invention resides inthe provision of a wagon having a sectional bed, vsectional in that thatportion between the front and rear wheels may bev one man to movev the wagon bed by the crank operated structure. He then can resort to the jaclcoperated structure, which gives the aided leverage necessary.

The preferred embodiment of my inventionis .shown in the accompanying sheets of drawings, in which similar characters of reference designates corresponding parts, and in which;

Figure 1 is a sidex elevation of my Wagon showing the bed in lowered position irA broken lines. 4 Fig. 2 is anend elevation of the structure shown in Fig. 1, looking toward the left, 3 is a view looking down on the operating mechanism carried by the rear portion of the vehicle, Fig. l is a section taken on line 114-4 of Fig. 3, and looking in the directionof the. arrows, Fig. 5 is a section taken on line 5-5 of Fig 3 and looking in the direction of the arrows, and, Fig. 6 is a View `showing the ,jack operating handle.

' In the drawings, the running gear is shown as `comprising front and rear wheelsl 1 mounted upon a suitable type of front and rear supporting structure deslgnated in Ats entirety `by the reference numeral 2.,

l`ach of the front and rear supporting structi res is also providedwith abcd portion 3, th `se bed portions being .so constructed as 'to 'ie in the same pla-ne with the major. or

movable bed portion shown at 4. Posts i 5y c and 6 extend upwardly one each side of each.

of the front and rearsupporting structures 2 and are bridged at their top by a rigidftie piece shown at 7. It is to be'understood that the general wagon structure maybeof 'any typerdesired, it beingessential only that'tie .pieces of some nature such as. are V shown at 7 are used, in order that the front and rear supporting structures 2 may be.

held in rigid connection. In order that theV lmovable and stationaryportions of the ve Y i i bien bedmay be heid in locked engagement so that the tie structure may be supple#V i r pair of locking members such asv shown at f f mented,1 have provided each side with a 8, each of these locking members beingpived to the Stationary Portions of the ve 'l' hicle by means of eye boltshown at 9, while their'opposite ends are provided with` eyes 10 in order that they-'may register ywith outwardly projecting. studs 1'1. locking members are held in their locked positions by means of clasps shown at r12,.-f` a the latter being pivoted at one end, as' Shown. at 13, to the body of the movableportion These, :di

ofthe bed 4. It will be understood thatby .i bringing the locking members 8. into en- 4 may be held in its looked position and in* this manner supplement the tie structure 7.

Ygagement with the studs 11, the`wagon-bed 'f f- In order to positively hold the locking mem?` bers in position, the clasp 1 members `12 `are .f

pr0vided,jthese latter operating in the manner shown particularly inFg. 1.

movable portion ofthe Wagon bed 4.,'1 `have provided an operating shaft 14, this shaft being suitably j ournaled upon the stationary portion 2 forming the support of the rear wagon wheels. Each end of this shaft isprovided with a double drum structure as shown at 15, upon which cables 16 and 17 are adapted `.to be wound, the cable 16 passing up along the side, of the rear posts 5, overawdouble sheave structure shown at 18 and-:then down. x e

to a point of attachment with the rear end 9o 'i i l In order to control the'moveme'nt of the f 'In order to operate the shaft 14, I have provided it' with a ratchet Wheel shown at 21, this ratchet wheel being rigidly mounted upon this shaft and being prevented from movingl in a reverse direction by means of the pivoted pawl shown at 22. In order to operate the ratchet, I have provided a jack pawl 23, 4this pawl being pivoted at 24 tov a -hollow rectangular casing25. This casingl is pivoted at 26to depending bearing members'shown at 27 and it is into this casing that the operating handle designated 28 and shownin Fig. G is adapted to fit. The pivoted end of the pawl 23 is also provided with a counterweight portion 29 in order -t'o always hold the forward end of the pawl in engagement with its ratchet. By inserting the operating handle 28 into the tubular casing 25, as shown in broken lines in- Fig. 4- and then moving the free .end toward the ground, the pawl 23 is given an upward movement and because of its engagement with the ratchet wheel 21, this ratchet wheel and its supportingshaft 14 are given a pan tial turn. The pawl 22 automatically falls in position by gravity to prevent reverse 'movement of the ratchet, which gives the operator an opportunity lof again moving the operating handle 28 up to get a second grip on the ratchet. This jack operating means is necessarily somewhat slow in aecomplishing the elevation of the movable portion of the bed and where the load being supported is such that an'unusually large amount of power is not required, the crank operating means shown in Fig. 5 may be resorted to. This crank operating means comprises a worm wheel 30 carried upon a sleeve 31, this latter being loosely mounted upon the shaft 14. Arranged to coperate with the worm wheel 30 is a worm 32 formed ona transverse shaft 33 suitably journaled in bearings shown at 34 and being provided with an operating crank 35 at its forward end. In order to provide some type of clutch arrangement to give a rigid connection .between the loosely mounted gear 30 and the shaft 14, I have pivoted a dog 36 to the ratchet wheel 21, as shown, this dog `being pressed toward teeth 37 on one face of the gear 30 by means of the leaf spring shown at 33. It will, therefore, appear that the gear 30 will rotate free of the shaft 14 in one direction and with this shaft in its oppo-I site direction because of the engagement between the rigidly lmounted ratchet 21 caused by the pivoted dog 36. This dog 36 is so arranged that rotation ofthe crank 35' to ro tate the worm 32 in a manner to cause elevation of the movable lportion'of the bed 4 will establish a rigid connection between the worm wheel 30 and the shaft 14. In the opposite direction, the weighton the movable portion 4 will be sufficient to at all times .keep the dog 3G .in engagement' with the yiaaaaoe l teeth on the worm wheel and this worm wheel is prevented rotating freely because of the driving connection it has with the worm 32. The loosemounting of the gear 30 on its shaft 14 is necessary for the reason that when the jack structure is operated, the ratchet wheel 21 and shaft 14 must rotate to elevate the wagon bed, while rotation of the4 worm wheel 30 is impossible unless the worm 32 is also operatedz y In order to renderA the jack operating structure inoperative to permit the use of `the crank operating structure, I have provided a shelf vmember 39 rigidly attached to a pivot bolt 40 carrying a crank 41 at its 'forward end. The shelf' under the control 4`of this crank 41 is so arranged that when its operative position, this inoperative posil` tion being also shown in dotted outline in Fig. 4, which inoperative position is caused by movement of the operating crank 44 to the left as shown in Fig. 2.

From the foregoing description, it will be apparent that I have provided a wagon of comparatively simple structure wherein the major portion of the bed may be moved between the ground line and the normal bed elevation. The structure for carrying out this operation is such that under comparatively light loads the movement may be effected rapidly, while under heavy loads the jack operating structure may be resorted to, which necessarily gives a somewhat,

slower elevation. Movement of the pawls 22 and 23 to the positions shown in dotted outline in Fig. 4 permits the use of a crankv operated structure wherein the worm and worm wheel 32 and 30 serve as a lock against accidental lowering movement of the bed portion 4. Operation of the crank 35 from the top down toward the left, permits the shaft 14 to rotate because of the applied weight on the bed. Movement of the crank 35 in an opposite direction, establishes a connection between the worm 30 and the ratchet wheel21 through the medium of the izo pivoted pawl 36 and, therefore, the shaft 14, v

will also be rotated notwithstanding the loose mounting of the gear 30. In this manner, the bed may be elevated. In case it is desired to use the jack operating structure, the operating cranks 41 arid44 are moved to the positions shown in Fig. 2, which permits the pawls 22 and 23 to assume the positions shown in Fig. 4. Insertion of the operating handle 28 into` the tubular casing 25 and oscillating it as is common will jcause this ratchet wheel 21 and consequently the shaft '14 to rotate to also elevate the Wagon bed-.

Because of the loose mounting of the worm wheel 30 on the rshaft 14, this wormwheel, but. if, for any reason, the pawl 2 should lbecome inoperative, the pawl 36 will serve as a check sincerit is always in engagement with the teeth on the face of the worm 30, and this worm is' locked against movement ybecause of its engagement with the worm 32611 the shaft 33.

What I claim, is: p 1. A wagon comprising a running gear, a

sectional bed, said bed being divided to permit movement up and down of that portion between the 'front and rear wheels, an -operating shaft, operating means connecting said shaft and the `I'nova le part. of said bed,

rotation of y the Ashaft and ratchet will be, free of the a Worm wheel loosely mounted on said shaft, a Worm arranged to. mesh wlth said worm wheel, a ratchet keyed to said shaft, .a jack operated said Worm Wheel.

3. A wagon comprising a running gear, a sectional bed, said bed being divided to permit up Width portion between the front and rear wheels, an operating shaft, .operating means connecting said shaft and the. movable part pawl arranged to coperate with said ratehet, and a ratchet and pawlconnection between said rst named ratchet and and downrmovementof the entire 1 of said bed, a worm, wheel loosely mounted upon said shaft,

to said shaft, a set of ed on the side' face of said ratchet and ar- 'ranged to coperate with said teeth, and a jack operated pawl arranged to coperate with said ratchet.

In testimony whereof I aix my signature in presence of two witnesses.
